摘要:
Any experimental studies related to vibration measurement cannot be conducted without calibration of sensors. The purpose of the calibration is to determine sensitivity of the sensors in the operating range of frequencies and amplitudes. To this end, we developed a method and installation is made with a unified software package in the LabVIEW programming environment. The results obtained by the piezoelectric sensor calibration setting showed the ability to calibrate any piezoelectric transducers in the frequency range above 100 Hz. When calibrating the sensor at a frequency less than 100 Hz, it is necessary to take into account the distortions associated with their own oscillation modes at the vibrating stand.
